It remains to be seen if I will use it regularly, but I do chatter nonsensically into twitter a fair bit and I am interested in things that allow me to type just a little less on some days ... so you never know.

What I kind of want is to magically be able to respond to twitter things with seesmic things, but that would involve convincing everyone I follow (or at least a good chunk of them) to use twhirl as well...
